Medical progress through technology, 17(3-4), 237-241 (1991-01-01)
The work presented is part of a design study for a Positron Emission Tomograph (PET) scanner based on the use of BaF2 scintillator and photosensitive wire chambers. The detection efficiency for gamma radiation of 511 keV is found close to

Optics express, 17(7), 5163-5169 (2009-04-01)
Bi-doped BaF(2) crystal was grown by the temperature gradient technique and its spectral properties were investigated. The absorption, emission and excitation spectra were measured at room temperature. Two broadband emissions centered at 1070 and 1500 nm were observed in Bi-doped

We show, using simulation techniques, that the high ionic conductivity in BaF2/CaF2 heterolayers is because the interfaces reduce the activation energy barriers to mobility and increase the number of charge carriers.

Medical progress through technology, 17(3-4), 243-247 (1991-01-01)
A detector has been developed for position sensitive registration of annihilation radiation. The 511 keV gamma rays are detected in a set of BaF2 scintillation crystals coupled to low pressure TMAE-filled photosensitive multi wire chambers. In a first experimental detector

Bismuth germanate (BGO) and barium fluoride (BaF2) scintillators are presently used in positron emission tomegraphy (PET) cameras. This study evaluates the important PET performance parameters of image resolution, true sensitivity, scatter background, accidental background, and realistic maximum radioactivity in the
